I am using biblatex/biber with several bibliographies for my book, and the misc-type, which is also a single bibliography (as a chapter), for legal documents. These documents often do not have a proper date or rather the date is part of the title. However, Latex gives me a "n.d." output, and I am wondering what I can do for it to not give a "n.d." when there is no year given?

To make clear, the reason for why I don't want to use the "year" field is that I deal with very different kinds of documents, which may either have no date or the date is in the title, because of which I prefer to simply "hard-copy" the whole thing in the "howpublished"-section and need to suppress the year, if none is provided.

MWE:

\usepackage[autocite=footnote, language=german, style=authoryear-ibid, sorting=nyt, backend=biber]{biblatex}
\usepackage[bottom]{footmisc}
\bibliography{lit.bib}
\makeindex
\begin{document}

Test\autocite[2]{draftnotice}.

\printbibliography[title={EU Legal Documents}, type=misc1]

\end{document}

My lit.bib is as follows:

@misc1{draftnotice,
    Author = {{COMMUNICATION FROM THE COMMISSION}},
    Howpublished = {Draft Commission Notice of 2014 on the notion of State aid pursuant to Article 107 (1) TFEU}}

    Could you post a minimal example? – Bernard Jun 15 '16 at 16:46

    Yes, but what is the @misc1 entry type? – Bernard Jun 15 '16 at 18:00
  • I have several bibliographies, among which several bibliographies with legal documents are. misc1 is European Union legal acts, misc2 is dutch legal acts and so forth. Otherwise it is not possible to filter them out. I will probably have to apply whatever solution i get to several of the misc-types. – kuuhkuuh Jun 15 '16 at 18:16

    I see. I didn't know one could add digits to standard types. – Bernard Jun 15 '16 at 18:40

Here is a way of selectively removing n.d.:

.bib file:

@misc1{draftnotice,
    Author = {{COMMUNICATION FROM THE COMMISSION}},
    Howpublished = {Draft Commission Notice of 2014 on the notion of State aid pursuant to Article 107 (1) TFEU}}
@BOOK{Dodgson,
    AUTHOR =    {Lewis Carroll},
    TITLE =     {The Hunting of the Snark},
    PUBLISHER = {Macmillan}

.tex file:

\documentclass[11pt, german]{book}
\usepackage[utf8]{inputenc}
\usepackage[autostyle]{csquotes}
\usepackage{babel} \usepackage[autocite=footnote, style=authoryear-ibid, sorting=nyt, backend=biber]{biblatex}
\usepackage[bottom]{footmisc}
\bibliography{mylit.bib}

\DefineBibliographyStrings{german}{%
nodate = {\ifboolexpr{test{\ifentrytype{misc1}} or test{\ifentrytype{misc5}}}{}{o\adddot D\adddot}},
}

\begin{document}

\vspace*{15cm}
Test\autocite[2]{draftnotice}. A book without date\autocite{Dodgson}.
\printbibliography[title={EU Legal Documents}, type=misc1]

\end{document}

    I don't understand: when there's no date, you don't want n.d. to be printed only for some entry types, and want it to be printed for all other types? – Bernard Jun 15 '16 at 18:53

    I have a solution, but you have to repeat the test for each miscxx type. – Bernard Jun 15 '16 at 19:56

    Just a question: Is your document main language german? – Bernard Jun 15 '16 at 21:07

    What you ask is already defined for all types of entries if you load babel with the german option. – Bernard Jun 15 '16 at 21:16

    Sorry, I had misread your code and thought you wanted to have o. D. in all cases. I'll try to see what can be done. – Bernard Jun 15 '16 at 21:36
